Impact Of Cyclone Nargis In Myanmar Environmental Sciences Essay

Impact Of Cyclone Nargis In Myanmar Environmental Sciences actIn May 2008, a very abominable cyclonic act1 named Nargis political campaignd the crush national natural casualty in the history of Myanmar. It killed al nigh 80,000 battalion and thousands of nation be still missing in this catastrophic tear downt1. The scourge cyclone was initiated in the stadium of secret convection, which was established in the Bay of Bengal, in late May and and so in ten-spotsified rapidly into a severe cyclone with the action of warm wet and upper-level tough1. This unwavering cyclone hit the glideal areas of Myanmar on May 2nd and brought serious reproach to these areas. In this essay, the study factor that contributed to such a tremendous deprivation of life during the storm will be first discussed and accordingly followed by the factors accounted for the great handicap afterwards the storm. The essay will be concluded with some issues regarding the pick of human beingness on the cyclones attack.High boot wave low gear and foremost, the mettlesome billow wave brought by the cyclone Nargis was the most significant cause for the great damage during storm. The massive soar which was trigge deprivation by cyclone brush outside(a) every clarifiedg like houses, lanes and other(a) infrastructure on its way in the inland area1. The 12 feet high wave swept away and deluge 50 % of house in the low-lying area. At least 10,000 tribe in Bogalay had died because of the storm surge1, it is a town 50 miles southwest of Yangon.flooding with some(prenominal) serious consequencesThe secondary effect was the flooding cause by surge in the low-lying area. Flooded sea pissing ruined the cultivation area and other residential places. The high salinity of sea water damaged the vegetations growth there as well. more importantly, the soil then became saltier which makes it unfavorable for the planting of vegetation and thus alter the food turn in in affected area evermore. In addition, flooding caused the mental block of road and this advance broke down the public transport network. People could precisely get through the inundate area and this caused inconvenience to people peculiarly the elderly. Moreover, the electrical energy power lines were damaged and this led to electricity shortage in the low-lying area for nigh six to seven geezerhood. Furthermore, the wells used to be providing clean water were submerged by the sea water. As a result, the clean water systems were polluted. To conclude, the food, electricity and clean water could non be found in the coastal area of Myanmar and this lack of resources further deteriorated the situation. Due to the absence of these terce basic survival elements for over quaternity days, the number of the death kept on increasing to an unimaginable level.planet images of floodingIn addition, the satellite image of Myanmar could demonstrate the destructive damage brought by flooding. In figure 2, it can be seen that rivers and lakes are sharp observed as there was a sharp boundary amidst them and both the vegetation and fallow agricultural area on April 15. The Irrawaddy River flows in the south direction and the Mouths of the Irrawaddy are formed by numerous distributaries 2. The deep blue green area near the shore was wetlands. Cyclone Nargis attacked directly the Mouths of the Irrawaddy and then moved to the northeast of coastline2. After 20 days, the coastal plain was deluge shown in figure 3. The agricultural areas had been totally destroyed and most of the coastal areas were covered by sea water. For instance, Yangon with population over 4 zillion was almost completely submerged by sea water whereas several tremendous cities with population from 100,000 to 500,000 experienced large magnitude of flooding2. The flooding false the coastal areas of Yangon into muddy places.Figure 2NASAs Terra satellite- Burma coast on April 15, 2008, onwards the arrival of Tropica l Cyclone Nargis Credit http//www.nasa.gov/topics/earth/features/nargis_floods.htmlFigure 3NASAs Terra satellite- Burma coast on May 5, 2008, Tropical Cyclone Nargis causes the devastation of flooding.

Cyclone Nargis was a strong Category 3 or minimal Category 4 hurricane with free burning winds of 130 mph and gusts of 150-160 mph3. The strong wind resulted in devastating damages to the environment. Since the area of Myanmar is very sad4, the houses were usually made only by thin woods instead of concrete. As the storm brought the strong wind to the coastal area, most of the houses were destroyed it was because they could not withstand the high speed wind. More importantly, the wind would bring all the debris and broken woods specially those from the houses along its track. This particularly endangered human lives in that a rea, as the high speed flowing woods could possibly destroy any lives or properties along its way within a few seconds. Therefore, human lives as well as properties were destroyed in large scale down the stairs the influence of strong wind.Aya, near the Ayeyarwady estuary in Myanmar. Cyclone Nargis caused significant land loss and coastal erosion. (Credit Hermann Fritz)Mudflow effectLast but not least, the mudflow was one of the factors cause large criterion of death in Myanmar5. The heavy rainfall brought by the cyclones saturated the muddy area with water and thus military press would be built up on the mud surface. When the combination of water pressure and gravity of the mud is larger than the resisting force, the high speed mudflow will occur. The mudflow which contained large amount of suspended particles and silt rushed into the coastal area, hence many an(prenominal) residents of low-lying rice fields were simply swept away in Maynmar4. It was estimated the death has be en to 140,000 cases or more. People were crashed with the broken woods in mudflow, swept away or suffered from suffocation4. Even worse, the mud flew on the coastal area prohibited the excavation of the buried people, making it more difficult. The mud jam the transport network which presented a difficult challenge to disaster centering and would result in serious damages.Poor management of world(prenominal) imprintFrom above, we have screened through the factors causing significant destruction during the passage of strong cyclone. Then, the discussion should move on to the factors of great damages after the storm. The check of international backing by the military government was a major reason for the great destruction of lives and properties6 after the storm. Many disaster judicial decision officials had to wait for few days in order to get the visa and enter area of Myanmar6. This further hindered the relief work as the international relief teams and private charity groups were not allowed to fully assess the situation. As the disaster could not be fully assessed, teams could not estimate the amount of relief materials and other supplies required promptly. Moreover, as mentioned before, Myanmar is a poor domain which does not have abundant relief technology and equipment to help extradite the buried people out of the mud flow. Due to the initial blockage from the military government, the international relief team cannot enter the affected areas promptly. This retard the time of the arrival of foreign relief teams and as a result, most of them arrived there after three days of the event. However, the survival time terminus ad quem of human being buried in debris or even mud was only forty-eight hours and this increase the number of death. In fact, when the teams finally arrived, they could only do little as the golden period had passed through6.The transnational Federation is stepping up its efforts to get food and water to those most affected b y cyclone Nargis.Credits http//www.ifrc.org/Docs/News/08/08051202/index.aspBlockage of assessIn addition, rise to power was a challenge for the rescue teams to face. The United Nation estimated that there are 1.4 million of survived victims who need resources like food, clean water, medicine and shelter7. However, most of the flooded area could not be entered by trucks. Instead, the helicopters were required to transport the relief materials. The situation worsened because the Myanmar government was too poor to have enough helicopters. Moreover, it took time in sending extra helicopters from other countries. Eventually, the officers allowed the first of ten helicopters from the World Food Program to carry food and water supplies from Yangon into the delta after a 10-day delay. The other nine were en route to Myanmar7. Some people died out of starvation as the supplies reached the intrusion area only after the ten days delay.Secondary damages of floodingBesides, the tidal surge dro ve inland from the sea caused secondary damage to the cities of Myanmar8. Three living quarters of livestock were killed and almost half the fishing fleets were sunk. Moreover, a million estate of the realm of rice paddies were salted by the seawater surges8. This flooding of seawater raceway the local food supply and inundated the low-lying area. Water pipes and electricity power lines were destroyed that people had to survive through four days without electricity and clean water. Even worse, the flooded areas remained flooded for a workweek and the water was contaminated by the dead bodies. There was a empty lack of sanitation facilities for the 500 people. said by an officer from red cross9. People had no choices but needed to drink the polluted water in order to survive. This led to the spread of water-borne diseases like cHYPERLINK http//en.wikipedia.org/wiki/Cyclosporiasisyclosporiasis and aHYPERLINK http//en.wikipedia.org/wiki/Amoebiasismoebiasis. Reports of digestive bo oklet disorders and malaria were heard and one in five people was reported nauseating9. In addition, the lack of transport resulted in a shortage of medicine. When people got sick because of drinking unclean water, their situations would probably worsen and they may die eventually. This caused a viscous cycle.Cyclonic storm1 named Nargis was the worst national natural disaster on the history of Myanmar. Both the natural and human factors greatly worsen the impact brought by cyclone which caused lots of death and damages. Natural factors like high surge wave, mudflow and flooding reconstructed the low-lying area of Myanmar whereas human factors like poor preparation for the cyclone and delay of the relief teams further worsened the situation and increased the number of the death and damages of properties. The coastal low-lying area of Myanmar originally had fertile soil and favors agriculture10. However, after the storm, all the agriculture areas were inundated by flood water and t he farmers lost all their farming products in three hours10. The power of nature cannot be modified by human being and this can be well demonstrated by the example that cyclone Nargis stricken Myanmar. Unfortunately, people had to earn money so they chose to stay there. On the other hand, Hong Kong, as an Asian city also, is always sheltered. Hong Kong people probably never give a serious thought on what will befall if this typhoon hit our city instead. Some of us might even entrust that the typhoons could attack Hong Kong directly so that there will be no working or school days. Hong Kong is a safe place that no one can remember the destructive typhoon and it leads to our neglect of unfortunate disaster elsewhere in the world. Should we change our attitude and understand more about how people suffer in the other part of world and in conclusion show more care to the unfortunate ones?
